Definitions
- the invention relates to a roller for a sliding door, in particular for an elevator sliding door consisting of a ball bearing, the inner ring of which is connected to a suspension bracket carrying the sliding door and flanges connected to the outer ring of the ball bearing, at the peripheral ends of which a tire made of plastic material is arranged, wherein the tire rolls on a roller conveyor of a carrier arranged on a door plate when the sliding door is opened and closed.
- a roller for a sliding door has become known, in particular for an elevator sliding door.
- the roller is held by a guide rail and carries a door leaf by means of a door hanger.
- the roller rolls on a guide rail.
- the roller consists of two flanges, a ball bearing and a tire.
- the flanges encompass half of the outer annular cage of the ball bearing and form peripherally a ring with a U-shaped cross section in which the tire is arranged with a tread.
- a disadvantage of the known roller is that the tire with a tread is temperature-dependent with regard to mechanical stability. If the door is not used for a long time at higher ambient temperatures, the tire is deformed under the door load, which leads to unpleasant running noises. In addition, such tires do not meet the fire protection regulations of elevator systems due to insufficient fire resistance.
- the invention seeks to remedy this.
- the invention as characterized in the claims, solves the problem of avoiding the disadvantages of the known device and proposing a roller that meets the requirements for smooth running and fire resistance of a sliding door.
- fire-retardant plastic materials for the running surface of a roller do not have the mechanical properties required for elevator sliding doors in terms of stability and service life.
- plastic materials that are mechanically suitable burn easily and therefore do not pass the fire test.
- the invention fulfills the requirement for a mechanically suitable roller and the requirement for a fire-retardant roller at the same time.
- the advantages achieved by the invention are essentially to be seen in the fact that the roller according to the invention has only small amounts of plastic materials without the mechanical properties in terms of stability, durability and smoothness being restricted thereby.
- the small amounts of plastic materials used in the roller allow the use of mechanically suitable plastic materials that are not particularly fire-resistant. It is further advantageous that the structure of the roller according to the invention can be applied to all roller diameters, which in turn has a favorable effect on the production costs thanks to mass production.
- 1 denotes a door plate, on which a carrier 2 with a roller conveyor 3 is fastened by means of a first screw 4.
- the roller conveyor 3 carries a roller 5 with a tire 5.1, which is connected to a hanging bracket 7 by means of a second screw 6.
- An elevator sliding door 8 is arranged on the hanging bracket 7. When opening and closing the elevator sliding door 8, the roller 5 rolls on the roller conveyor 3.
- the roller 5 consists of a concentrically arranged ball bearing 9 with an inner ring 10 and an outer ring 11 and a bore 12 penetrated by the second screw 6, the outer ring 11 being covered laterally by a first annular flange 13 and a second annular flange 14.
- the two flanges 13, 14 are held together at the peripheral end by rivets 15, so that the outer ring 11 is clamped between the flanges 13, 14.
- rivets 15 screws can also be used.
- the peripheral space between the outer ring 11 and the flanges 13, 14 is filled with a tire made of plastic material in the rollers known from the prior art.
- an inner reinforcement cage 16 and an outer reinforcement cage 17 are inserted into the peripheral space in the tires 5.1 and this is filled with plastic material.
- the plastic material used has suitable mechanical properties in view of the load to be carried, but is in itself not very fire-retardant. Because of the small amounts used and because of the connection to the reinforcement cages 16, 17, the roller 5 is not flaming in the event of a fire but only carbon.
- the inner reinforcement cage 16 lies within the rivets 15 and so far from the outer ring 11 of the ball bearing 9 that space for a minimal first layer 18 of plastic material between the outer ring 11 and the inner reinforcement cage 16 remains open.
- the outer reinforcement cage 17 comprises the rivets 15 and is covered with a minimal second layer 19 made of plastic material, the second layer 19 having a profile corresponding to the roller conveyor 3. A third layer, not shown, of plastic material is arranged between the two reinforcement cages 16, 17.
- the layers 18, 19 serve to dampen noise, while the reinforcement cages 16, 17 serve to provide mechanical stability.
- the reinforcement cages 16, 17 consist of stiffening rings 20, which are held apart by spacers 21. Instead of the stiffening rings 20, corrugated washers can also be used, which are mutually separate due to their wave shape.
